Which is why a system based on policing corruption through public outrage is doomed to fail. You need to have a system that has actual mechanisms--investigations, prosecutions, and convictions--to keep a lid on corruption. Public shaming doesn't work because the public has only so much attention span, and there is soooo much corruption.
Which, I know, is very frustrating to those who are salivating at the thought of seeing them provoked. The unanswered cries of "where's the 2FA crowd now?!" have, admittedly, been very satisfying to watch.
Unfortunately, the media only drops these things when it's a politician they like. Anyone right of Obama gets hounded with scandals, real or imagined, as often as possible, forever.
I'm not sure this is true. My experience is that either the mob is destroyed by force, or they manage to convert enough out of fear that they end up controlling the institution they were attacking.
